Highly suppressed detection probability of the primordial antimatter in the present-day universe

Abstract

We show that the matter-antimatter asymmetry in the present-day universe is mainly due to the highly suppressed detection probability for the primordial antimatter, which is a direct result of the Dirac-Feynman-Stueckelberg interpretation of antimatter and the extremely time asymmetric expansion of the primordial universe.

Figures (3)

• Figure 1: The illustration of particle's detected entity (red dashed line) and wave function (blue line) both with interpreted positive energy propagating forward in time, and the antiparticle's detected entity (orange dashed line) with interpreted positive energy propagating forward in time and the wave function (green line) with negative energy propagating backward in time.
• Figure 2: The evolution of the radius of the universe. The expansion of the universe with the inflation is shown in the blue line and the standard Big Bang theory is shown in the dashed red line.
• Figure 3: The notations are similar as Fig \ref{['fig:propagation']}. Gray area indicates the accessible space (in log scale) in the lepton (hadron) epoch. The light blue stars are the places when wave functions for particle and antiparticle collapsed.
